2. Pivot yoke shoulder 4. Lower bushing
7. Inspect the flange bushings in the lift arm and pivot yoke for wear or damage.
If necessary, replace the bushings as follows ( Figure 314 and Figure 315 ):
Note: Do not damage the bore of the lift arm and pivot yoke during bushing
removal.
A. Use a bushing removal tool to extract both the flange bushings from the
lift arm or pivot yoke.
B. Clean inside of the bore to remove any dirt or unwanted material.
C. Apply grease to the inner and outer surfaces of the new bushings.
D. Use an arbor press to install the bushings into the lift arm or pivot yoke.
The lift arm bushings should be pressed until the bushing flange is
against the lift arm bore. The upper pivot yoke bushing should be pressed
fully to the shoulder in the pivot yoke bore. The lower pivot yoke bushing
should be flush with the yoke tube.
E. After bushing installation, ensure that the lift arm slides easily onto the
pivot shaft. If there is any binding, locate and correct the source of
binding.
8. Check the lift arm pivot shaft (item 3 in Figure 312 ) for wear or damage. If
necessary, remove the roll pin that secures the pivot shaft to the frame, and
remove the pivot shaft from the frame. Discard the roll pin.
Installing the Front Lift Arms
1. If the lift arm pivot shaft (item 3 in Figure 312 ) was removed from the frame,
apply anti-seize lubricant to the pivot shaft surface and insert the shaft into
the frame. Align the holes in the frame with the pivot shaft. Secure the pivot
shaft with new roll pin.
2. Slide the front lift arm onto the pivot shaft.
3. Apply medium strength threadlocker to the threads of the bolts (items 7, 8,
and 9 in Figure 312 ) that secure the bridge plate (items 5 or 17 in Figure
312 ). Secure the lift arm to the machine with the bridge plate. Torque the
bolts that secure the bridge plate to the torque values identified in Figure 312 .
4. Position the thrust washer (item 15 in Figure 312 ) onto the pivot yoke shaft,
and slide the pivot yoke into the lift arm bushings. Place the second thrust
washer on the pivot yoke shaft and secure with the lynch pin.
5. Connect the lift cylinder to the lift arm (item 1 in Figure 313 ) as follows:
A. Align the lift cylinder rod end with the lift arm mounting hole.
B. Slide the cylinder pin with the retaining ring and thrust washer through
the lift cylinder and lift arm.
